These megaliths were retrieved from the Tuxtla Mountains and transported a distance of at least 80km to their principal centre at San Lorenzo. The methods and routes used are uncertain, but water-based routes using rafts have been considered the more likely strategy. Of two watercraft types proposed, a log raft configuration has been more favoured. This research examines the possibility that rafts were used and considers structural viability and as the primary motive force, human physiological capabilities. Analyses were undertaken of both raft and crew and their combined performance under these loads. Maritime and meteorological factors found in the Gulf of Mexico were also applied to technological parameters. These analyses show that a log raft configuration would not have been a viable means to move such highly valued stones upstream on rivers, nor over open water.
